The latest Revo 3.3 (TRA5308) and T-Maxx 3.3 (TRA4908) models use forward-only transmissions to reduce rotating weight and maximize acceleration and top speed, but Traxxas hasn’t forgotten those drivers that prefer the versatility of a reversing transmission. Reverse Installation Kits are now available for both models, with full instructions and all required hardware—right down to a sub-micro servo to operate the shifting mechanism. The Revo 3.3 and T-Maxx 3.3 include 3-channel radio systems, so you’re ready for reverse as soon as you install the kit. Whether you just need to back your truck out of trouble or want to add stunt moves to your next driving session, the Reverse Installation Kit is all you need to shift into “R.”
